. capacity to provide a constant hot water sup ply for the averagehousehold.

With the above and other objects in view as will hereinafter clearlyappear, my invention comprehends a novel combined hot water heater andstorage tank.

Other novel features of construction and advantage will hereinafter moreclearly appear in the detailed description and the appended claims.

For the purpose of illustrating the invention, I have shown in theaccompanying drawings preferred embodiments of it, which, in practice,will give satisfactory and reliable results. It is, however, to beunderstood that these embodiments are typical only, and the variousinstrumentalities of which my invention consists can be variouslyarranged and organized, and the invention is not limited to the exactarrangement and organization of these instrumentalities as herein setforth.

Figure 1 is a front elevation of a combined hot water stove and storagetank, embodying my invention.

Figure 2 is a section on line 2-2 of Figure 1.

Figure 3 is a section on a reduced scale on line 3 3 of Figure 2.

Similar numerals of reference indicate corresponding parts.

Referring to the drawings 1 designates a hot water heater of thedomestic type with which is combined a storage tank 2, which ispreferably in vertical alignment therewith.

The hot water heater' 1 is provided with an outer casing 3, which isinsulated as at 4, the insulation being outwardly of the outer waterjacket wall 5, which with the inner Water jacket wall 6, forms the Waterjacket chamber 7, 3 and 9 designate downwardly inclined baHes, thebaffle 9 being longer than the baffle 8, and these two baffles arehollow and infree communication with the water jacket chamber and formwater legs extending completely across the cylinder formed by the innerwater jacket wall 6. l Y

The juxtaposed side walls of the baffles 8 and 9 extend to and areconnected with the v outer water jacket Vwall 5. The balile 8 forms theroof of the combustion chamber 10 and contributes with the baffle 9 toform the exit Hue 11 which leads from the combustion chamber 10 to thesmoke box l2.

The top wall of the baille 9 partially supports the fuel in the fuelmagazine 13, which is provided with a door 14. The fuel passes from thefuel magazine through the throat 15 to the fuelbed 16 which is supportedby an inclined grate A17 having an operating handle 18. Y

The shaking movement of the grate is in a rectilinear direction anddelivers the ash to a pan 19 in the ash pit 20 having a door 21. 22 is acontrollable drain from the water jacket chamber 7. The upper end of thehot water stove is closed by the bottom wall 23 forming the bottomheader of the storage tank. This bottom wall is sealed with the upperends of the water jacket walls 5 and 6 and seals and closes the top ofthe fuel magazine.

The bottom wall 23 is sealed withthe cylinder 24 which is sealed withthe top header 25. rlhe cylinder 24 is surrounded by insulation 26 whichalso extends overthe top header, and an outer casing 27 is provided.

The cold water inlet kpipe 28 passes through the top header andterminates a desired distance above the bottom header 23, The hot waterexit 29 from the hot water magazine 30 leads to a desired point ofutilization;

Ports 31, see Figure 3, permit the hot water to pass by gravity from thehot water magazine 3() to the chamber 7 The hot water passes from thechamber 7 through slots 32 into a funnel-shaped fitting 33 whichdischarges into the pipe 311 which terminates a desired 'distance fromthe top header 25.

35 designates an automatic damper control of any desired or conventionaltype which communica-tesat 36 with the hot'water magaj zine and iscontrolled by the temperature of the hot water. This dampercontrol 35,is connected by a cable 37 and conventionallinkage with a damper 38 forthe smoke box 12 and by a cable 39 and conventional linkage with adamper 40 controlling introduction of atmospheric air to the ash pitiorprimary combustion.

The operation will now be clear to those skilled in this art and is asfollows I In order to start the heater, the kindlings are introducedthrough the door controlled opening 4:1. Thexcold water entersfrom thesource of cold water supply through the 28. The cold water in thehotwater magazine passes through the ports 31 into the water jacket chamber7 Vcreating an unbal anced condition in the hotwater magazine 30. Thehot water passes the. baiii'es' and 9 intothe slots'32 innthewbottoniheader into' the itting 33 and rtlreriafronr to the pipe 34;. Therhotwater is' withdrawn through the pipel 29. As the temperature of the'water increases to va desiredA` standard, the automatic control 35Icauses the' damper 38 to open and the damper l0 to close.'4` i j l Inmy present invention, I combine a unitary structure, a gravity fed fuelmagazine heater and a hot water storage tank with an automatic dampercontrol 'of the source of heat. This enables one to operate the devicefor a-period of at least twenty-four hours without any attention on thepart of the operator. At the endk of such period, the grate should beshaken and the coal maga- ZHG filledv Y n My combined hot water heaterand storage tank can be manufactured at a much less cost than where aseparate tank is used; and the costof installation is also materiallyreduced.

Special attention is directed to the novel v construction andarrangement of water legs cornniunicatingin a novel manner with thelozottom header of the storage tank.v The hot water passesdireetly fromthe water jacket into ,thel storagewtankwith 1ro` losses dite toradiationor other causes" as isthe case where the heater and tank areseparated and connected by outside pipes and fittings; i

Having thus' described my invention what I claim as new and desire tosecure by'Letters Patent, is v l. A domestic het water heater having incombination a water jacketed coalheate'r and a storage tank, arrangedone above the' other and forming a unit of structure, said heater jackethaving at its upper en'd downwardly inclined water legs in directcommunication with lsaid jacket and Jforming the exit for the productsof combustion, anda connection from one of said legs leading through thef bottom of the storage tank and discharging near the top of the latter.Y

2. A domestic hot water heater having in combination a water jacketedheater and a storage tank, arranged one above thewother and forming aunit of structure, said heater inclined water legs in directcommunication with said Water jacket and forming the exit for theproducts of combustion, one of said legs having a communicationdischarging into said storage tank near its upper end, said heaterhaving a coal magazine which is c'los'ed by the bottom of said storagetank, and one wall of said magazine is formed by one of said water legs.
